The greater occipital nerve is a nerve of the head. It is a spinal nerve , specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2 . It arises from between the first and second cervical vertebrae , ascends, and then passes through the semispinalis muscle .
The medial branch (ramus medialis; internal branch), called from its size and distribution the greater occipital nerve, ascends obliquely between the Obliquus capitis inferior and the Semispinalis capitis, and pierces the latter muscle and the Trapezius near their attachments to the occipital bone. It is then joined by a filament from the ...

It remains a common practice to utilize a landmark-only approach when performing greater and lesser occipital nerve blocks. For blockade of both nerves, medication is infiltrated along the nuchal ridge. This technique, while easy to perform and relatively safe if done correctly, may not be particularly accurate and as a result, could ...
These include the greater occipital nerve, which provides sensation to the back of the head, the lesser occipital nerve, which provides sensation to the area behind the ears, the greater auricular nerve and the lesser auricular nerve. The phrenic nerve is a nerve
Occipital nerve block is a procedure involving injection of steroids or anesthetics into regions of the greater occipital nerve and the lesser occipital nerve used to treat chronic headaches. These nerves are located in the back of the head near in the suboccipital triangle along the line between the inion and the mastoid process .
Therapies acting on the vagus nerve (cranial nerve X) and the greater occipital nerve have both shown efficacy in managing cluster headache, but the specific roles of these nerves are not well-understood. [6] Two nerves thought to play an important role in cluster headaches include the trigeminal nerve and the facial nerve. [30]
